MTSMC-L4E1-U Equivalent & Substitute Parts

Part Overview

The MTSMC-L4E1-U is a cellular and navigation 4G LTE CAT-3 transceiver module manufactured by Multi-Tech Systems Inc. as part of the SocketModem® Cell series. This module operates across multiple frequency bands (700MHz, 800MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz) with a maximum data rate of 150Mbps and features USB serial interface connectivity. The module uses U.FL antenna connectors with through-hole mounting and operates within a supply voltage range of 3.3V to 5V across an extended temperature range of -40°C to 85°C.

The MTSMC-L4E1-U is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing system deployments where this module is integrated.

Substitute Part Grouping Explanation

Substitute parts for the MTSMC-L4E1-U are identified based on strict equivalence across the following critical parameters:

• RF Family/Standard: Cellular, Navigation
• Protocol: 4G LTE CAT-3
• Frequency Bands: 700MHz, 800MHz, 900MHz, 1.8GHz, 2.1GHz, 2.6GHz
• Data Rate: 150Mbps
• Serial Interfaces: USB
• Antenna Type: U.FL connector configuration
• Voltage - Supply: 3.3V ~ 5V
• Mounting Type: Through Hole
• Operating Temperature: -40°C ~ 85°C
• Package / Case: Module
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The MTSMC-L4E1-U.R1 variant meets all these criteria and is classified as an active product, making it a direct functional equivalent suitable for replacement in applications currently using the obsolete MTSMC-L4E1-U.

Parameter Comparison

Engineering Selection Recommendations

The MTSMC-L4E1-U.R1 is the direct substitute for the obsolete MTSMC-L4E1-U. Both parts are manufactured by Multi-Tech Systems Inc. within the SocketModem® Cell series and maintain identical electrical, mechanical, and environmental specifications. The MTSMC-L4E1-U.R1 carries active product status, ensuring ongoing availability and support.

Both parts comply with ROHS3 regulations and carry MSL Level 1 (Unlimited) moisture sensitivity classification. The primary distinction is product lifecycle status: the MTSMC-L4E1-U is obsolete while the MTSMC-L4E1-U.R1 is active. The MTSMC-L4E1-U.R1 is supplied in Tray packaging, whereas the original part number does not specify packaging details.

For new designs or system refreshes, the MTSMC-L4E1-U.R1 is the appropriate selection. For existing systems currently deployed with the MTSMC-L4E1-U, the MTSMC-L4E1-U.R1 provides functional equivalence without design modification.
